NOTE.—The Branch Hydrographic Office, Honolulu, T. H., inaugurated on Dec. 1, 1945, a broadcast series of radio dispatches known as Hydropacs for the Pacific Ocean area. These messages, serially numbered, contain all information on mined areas, swept channels, and other war-created dangers not previously published in the regular Notices to mariners. In addition any urgent hydrographic information of a permanent nature is issued in the Hydropac numbered series. Ephemeral information such as reports of drifting mines, wreckage, temporary deficiencies in aids to navigation, etc., is the subject of unnumbered Hydropacs. The publication here cataloged contains printed summaries of all effective Hydropacs.
